"He goes to the Rules of Acquisition. Unabridged and fully annotated, with all 47 commentaries, all 900 major and minor judgments, all 10,000 considered opinions. There's a rule for every conceivable situation."

Gint's lifetime or when the Rules of Acquisition were first created was never mentioned on-screen. However, in "Little Green Men", it is stated that it "took [ten thousand years] to establish the Ferengi Alliance", which might imply Gint lived circa 8000 BC, if he is considered the founder of the Alliance.

There was also a short-lived revised edition of the Rules written by Grand Nagus Zek after having his state of mind changed by the BajoranProphets. These rules were almost complete opposites of the original rules and promoted honesty and charity. After Zek recovered, he ordered all copies of the new rules to be destroyed. (DS9: "Prophet Motive")

↑Brunt stated a variation of this rule (without referring to it by number) with: "It's never too early to suck up to the boss".

↑Quark stated a corollary: "only from a distance, the closer to the front lines, the less profitable it gets"

↑Although spoken before the production staff's creation of the Rules of Acquisition, Par Lenor stated something quite similar to this rule: "Peace is good for trade … unless you happen to be an arms merchant!"

↑ 8.08.1Rule of Acquisition #95 was quoted as Rule #45 in ENT: "Acquisition". It might be possible though, that in the roughly two hundred years between the two episodes, the arrangement of the Rules of Acquisition slightly changed. Alternatively, it may have been decided that the rule bears repeating. Indeed, this may be self-referential.

↑This rule was actually only called "one of the high numbers" by Quark; he only thought it was rule 194.

↑In DS9: "Body Parts", it is suggested in a dream of Quark's, that the Rules of Acquisition themselves are merely guidelines, and the book was mislabeled by Gint so as to sell more copies than the "Suggestions of Acquisition." However, this may be no more than Quark trying to justify breaking rule #17, since this rule is obviously higher than ENT's "original" 173 rules. It could also be noted that the Grand Nagus has the power to change the Rules of Acquisition, so it is still possible this rule changed position over time (DS9: "Prophet Motive").

↑Though not given a number, this rule was clearly official, among the first 173, and considered "the most important one" by Krem.

↑Personal rule of Quark's. Rom noted there was no such rule, to which Quark replied that there should be.

↑Is likely a purely fictional rule, as it was quoted by Neelix, who had no previous contact with Ferengi, and it did not exist by the time the target Ferengi became stranded in the Delta Quadrant. Neelix claimed at the time that Kol had been away for a long time to suggest that new rules had been written. It could be consistent if Neelix had found some encrypted appendix in the Ferengi shuttle that Kol had not read.

↑This saying was quoted by Brunt to Quark. It is unknown whether it was an official rule or not. According to Star Trek Online, it is rule 240.

↑Not quoted word for word, but when Sisko asked if such a rule existed, Quark acknowledged that there was. Quark may have been referring to the apocryphal Rule 218 (see below). According to Star Trek Online, this is rule 272.

↑As told to Odo by Quark when the latter illegally used replicators in empty crew quarters. He seems to have been paraphrasing the apocryphal Rule 52 (see below).

↑Quark told the Wadi delegation visiting his establishment that this was an old Ferengi saying.

↑This un-numbered "rule"'s provenance derives merely from Janeway quoting it as something "the Ferengi say". It may not, therefore, have been a genuine Rule. The apocryphal Pocket DS9 title The Long Mirage, however, explicitly describes it as a Rule, but does not give it a number.

↑Rom said this to Quark when urging him to complete a very important mission that could end with the two being killed. From the implicit understanding Quark displayed, and the lack of prior reference to any "written" materials, it's likely that this was in fact a Rule, probably referring to the finality of a business contract, here used out of this original context. According to Star Trek Online, this is rule 227.

↑Quark says this to Jake in the opening of the episode upon noticing Odo's love for Kira is a distraction.
